Power converters in electric vehicles, aerospace applications or renewable energy applications need to be able to transfer large amounts of power, while being compact and reliable. In motor drives for traction, this ever growing demand for high power densities also meets a very challenging thermal environment, because of…
Problem Opening an old CADFEKO [LEGACY] model in CADFEKO fails to convert to the new format. Cause CADFEKO uses advanced mapping algorithms to keep track of individual items when the geometry is modified. A model that was saved in an earlier CADFEKO [LEGACY] may not have all the mapping information available. Remedy * Open…

Custom HyperWorks features (scripts, process automation, general customizations etc.) are typically developed for a specific version using the set of tools and APIs available in that version. If we want to verify the compatibility of a script with an earlier or a newer version, we can simply run it there. However, manually…
How to calculate an integral or derivative using capacitors and inductors As you progress with your simulation abilities it will become clear that there isn't a pre-built library element to describe every single model type that you might need. It will become necessary to be able to model math equations of derivatives and…
An NTC is typically used to limit inrush currents, it is essentially a resistor that has temperature dependency. When the element is cold the resistance is larger and when it is hot the resistance is lower. This is the key functionality that needs to be modeled an element that heats up, that has a changing impedance with…
Power supplies are the backbone of the electrified world. Converter requirements, advancements in switches, magnetics, topologies, and control techniques require you to have a dynamic, fast, accurate, and purpose-built simulation tool for power electronics. Powersim has been providing simulation tools for power supplies…

Modelling a TVS with PSIM A uni-direction TVS can be modelled with a zener diode. A bi-directional TVS can be modelled with two zener diodes, connected cathode to cathode From Littlefuse Breakdown Resistance We can calculate the resistance of the device by using the breakdown voltage and current to calculate the slope of…
